Huffer - In the season three episode "Dark Awakening," Huffer is listed among the war fatalities.

Smokescreen - original storyboards featured Smokescreen's dead body in place of Wheeljack's

Beachcomber is briefly seen at one point in the movie, preceding Spike on a conveyor line of robots that are about to be dropped into Unicron's stomach acid. We all know what happens to the bots before Jazz and the other 4 guys.

Huffer and Brawn didn't die! Seriously, check out "Carnage in C-Minor"; theres one brief scene where they're stand around shooting at.. something.. with the Constructicons . Ah, one of the many mistakes that made that episode so bad it hurts.

Wheeljack, Beachcomber, Dirge and Ramjet didn't die in the movie. Dirge and Ramjet died in FFOD, when Ultra Magnus punched them, they exploded, never to bee seen again. Beachcomber was in FFOD when the mini-bots attacked a newly built Trypticon.
